Should we name it "imx6qdl-prt-common.dtsi"? Still don't like that this
dtsi comes from the 1st commit rather then having a single commit adding
the .dtsi but that is only my opinion.

Do you need this fine granularity here? Just asking ;)

Don't know if there is a common rule if the gpio key should be sorted
alphabetical too.

Did you send a patch for this panel?

Nit, it's common to allign the pahndle and the name, so either:
reg_12v_bl -> regulator-12v-bl
or
reg_bl_12v -> regulator-bl-12v
also it would be cool to keep the first digit after the point like you
did it for the 1.8 regulator. So the result would be:
reg_12v0_bl -> regulator-12v0-bl
or
reg_bl_12v0 -> regulator-bl-12v0

The this should be listed within the binding doc.

IRQ and the GPIO are the same gpio line?

Why do you disable this nodes? You should drop it from the common .dtsi
if you disable them more than once.

Why do you mux the the camera interface and have no camera device within
this dt.
